I just put a 128MB stick of RAM in my Cisco 877 and rebooted it. Everything works as normal, except for the fact that I can't log in via SSH. Specifically, I receive a 'connection refused' message when I try to connect. As I said, everything else (access lists, internet, logging) works fine.

Any ideas why this might be?
 
I'm not saying it has, but if you have checked ssh is enabled, and the acls are ok, I'm going for the next obvious thing to check. I'm a bit of a pain with diagnostics, because I start with the obvious and work towards the really unlikely (like have you checked if its a wanning moon?)
 
Thing is, I've got 5 millions console cables, and zero computers with serial ports. Need to go buy a USB->serial adapter before I can check things over the console. Appreciate what you're saying though, I've had cisco key generation problems before, but they've usually manifested themselves by not allowing an ssh client to authenticate, rather than flat out refusing the connection.
 
Ok, this is weirdness - I've got a USB/Serial adapter, and when I plug it in it gets detected and the drivers installed. However, as soon as I plug the cisco console cable in, I get a 'USB device unplugged' sound in windows and the COM port disappears.

WTF?
 
USB>Serial are the damn devil.

I have used 2 different ones from completely different manufacturers and I only ever get garbled console output.

Get a proper PCI one.
 
We use Keyspan. They work fine. Even the cheaper ones work fine but they tend to break easily.
Check that your USB to Serial isn't using an already used com port.

Are you sure you was connecting at the correct speed? I remember at one of my CCNA day schools last month, lots of people got garbled text when trying to use hyperterminal to connect to the router, which turns out it was because they didnt listen and tried to connect at the default speed instead of lowering it. Once lowered the output was as it should be.
 
I use a Belkin USB > Serial convertor and that works without a fuss, i know i have read a number of reviews about some types of convertors not working though.

Yep, cheap old IBM with a serial port are great.

I also have a Belkin USB-Serial that seems to work perfectly well with all of the Cisco / HP kit I've connected it to in the past.
